Unlike Attenborough’s other films, which mostly celebrate the wonders of life’s diversity, Ocean (2025, 1 h 35 min) focuses on the devastating destruction of our world’s vital marine ecosystems. The film rightly addresses the main problem: overfishing and the fishing industry’s destructive techniques. The film advocates marine protected areas (MPAs), fishing techniques that do not involve discarding three-quarters of the catch, and highlights the importance of the ocean in binding carbon dioxide.
